she thinks she is losing her lord and master and beloved teacher
While it is true, as stated explicitly in Scripture, that the disciples remained ignorant of the need for Christ's death and the inevitability of His resurrection, I cannot help but suppose that Jesus had let His mother in on the whole story. So, if true, then she knows she is not "losing her lord and master and beloved teacher"; her anguish becomes no less intense, but she cries only the ordinary tears a mother has when watching her child suffer..
I think it was her that was shocked and overwhelmed that christ was not In Tomb, no? Or was that the other mary?
The painting was of Mary magdelan whom heretics claim was the ‘wife of jesus’
11 Now Mary stood outside the tomb crying. As she wept, she bent over to look into the tomb 12 and saw two angels in white, seated where Jesus’ body had been, one at the head and the other at the foot. 13 They asked her, “Woman, why are you crying?” “They have taken my Lord away,” she said, “and I don’t know where they have put him.” 14 At this, she turned around and saw Jesus standing there, but she did not realize that it was Jesus. 15 He asked her, “Woman, why are you crying? Who is it you are looking for?” Thinking he was the gardener, she said, “Sir, if you have carried him away, tell me where you have put him, and I will get him.” 16 Jesus said to her, “Mary.” She turned toward him and cried out in Aramaic, “Rabboni!” (which means “Teacher”). 17 Jesus said, “Do not hold on to me, for I have not yet ascended to the Father. Go instead to my brothers and tell them, ‘I am ascending to my Father and your Father, to my God and your God.’” 18 Mary Magdalene went to the disciples with the news: “I have seen the Lord!” And she told them that he had said these things to her.”
